If it befuddles automated software that collects phone #s for telemarketing purposes, it's actually a good thing. Just like any public posting will have my e-mail addy written as "name (AT) site (dot) com."

Personally, I prefer the way a few older stores in my area still have numbers on their signs written thusly:
REgent 4-xxxx or CIrcle 9-xxxx.

My e-mail sig has my landline number as +1.212.xxx.yyyy.

And until about 10 years ago, my uncle's phone number was just "42." Small town in Poland -- you dialled the operator, got put through to the operator in his town, and asked for the number. Parse THAT, beeeyotches.
